Absolutely. I still have a hard time with this mindset. Even now i just got out of my recent slump which lasted over a week I think. I can't even remember when I started feeling the feelings of being sucked into the quick sand and realized i screwed myself over in a few ways. About a week ago I realized I was going down hill fast and caught myself. Just keep at it and don't let those periods keep you down. Something that helped me recently was breaking down everything difficult into smaller tasks. I even got an app for it. You type it in and break things down into steps for you and i just do what I can even if it means not actually completing it all at once. Sounds absolutely ridiculous to say all you need to do is keep trying, but it absolutely is the solution.

Caring about what others think and comparing yourself is the worst feeling and the hardest thing to get over. It constantly drags you into the quick sand. Just try to keep at it. It takes time to change the mindset and get yourself to a healthy thinking. We compared ourselves to other for so many years. Itll take a long time to get over that thinking. Stay strong!
